okay so I've been thinking about this for a while I've read of tortoises and box turtles that are being or have been kept in glass terrarium cages getting stressed and constantly trying to crawle through the glass. I for one have never seen this. In my expieriance once they know where the walls are they don't try to go through them. though some individuals climb out of them. my question is what is your expieriance? oh to clarify (not sure if that is correct) i don't mean standard width aquariums i mean like 40 breeders, 75s, 100 breeders and such wider tanks. thanks for your input
